[Feature request] Enabling MinSize as part of Netgen 2D hypothesis

Currently (in 5.1.5) Netgen 2D hypothesis only provides the max size parameter (in addition to grading, nb_seg_per_edge, etc). Netgeun it slef, however, offers more than that, and, in particular, the min size. Salome defaults it to 0 which can lead to infinite loops on some 3D models. For instance, the attached model can be successfully meshed with setting min_size=10, max_size=15 programmatically but fails to be meshed with max_size=15 when set in GUI. Such sensitivity can probably appear on NURBS surfaces/curves with non-uniform parameterization.

So, please do consider extending GUI and API to support the min size parameter. To ensure consistency with prior versions it can be defaulted to zero.

Hi Roman,Indeed, it is a good idea to add the min size parameter in salome netgen plugin.Unfortunately, the next version (6.3.0) is now on the rails (near the internal release candidate) and the feature integrations are now closed.I will check if it can be done for 6.3.1.Regards, E.A.
